Like a Butterfly, Vol. 4 (manga)

Suiren’s heart feels like it’s going to burst - Kawasumi offered to walk her home! With each step, she can feel herself growing closer to him, and even Kawasumi believes things are too good to be true. While Suiren works up the courage to ask if Kawasumi will take her to the upcoming school cultural festival, they both can’t help but wonder - are they still just classmates, or are they something more?
